Slow Closing Mechanism For Toilet Covers

ABSTRACT

Slow closing mechanism (A) for toilet covers according to the invention comprises left hinge shaft ( 1 ), right hinge shaft ( 2 ), main frame ( 3 ) and toilet fitting legs with slots ( 4 ) on the main frame ( 3 ), damper housings ( 5 ), compressing member ( 6 ) and slow closing dampers ( 7 ) and enabling easy fitting and disassembly on existing toilet covers without any modification.

TECHNICAL FIELD

This invention relates to a mechanism frame providing slow closing fortoilet covers.

BACKGROUND ART

The mechanisms providing smooth closing of toilet covers have beenmanufactured for many years. In the prior art, for slow closing oftoilet covers, mechanisms and frames hereof attached to the toilet havebeen well known. These mechanisms and/or frames hereof are problematicowing to the fact that they contain many parts, have complex structure,lead to bulkiness on the toilet, cause difficulties in assembling andmaintenance hereof.

In the prior art, hinge mounting member of slow closing damper is usedwhich is applied in industry and fitted on the toilet mounting holesseparately and not connected to each other with a frame member. Thissystem is characterized by being suitable for all kinds of toilets andtoilet covers, but there is a mounting difficulty owing to the fact thatframe and damper recesses are not connected to each other.

In a further prior art, the hinge mounting member of slow closing damperis single-frame wherein slow closing dampers are fixed into recesses bya claw coupling. However, there is a mounting difficulty owing to thefact that plastic attachments coupled into hinges of the slow closingare of single-piece. During assembly a single-piece mounting member ispre-fitted on the damper and then attached to the hinge recesses.However, due to this single-piece mounting member remains attached intothe hinge recess, it is very difficult to replace this part duringdisassembly. Even if slow closing dampers are attached on the toiletcover, later has to be detached from the toilet during disassemblyentirely as it is.

Moreover, toilet covers with a slow closing feature in the prior artpatents/patent applications No. DE10020180, DE3718705, U.S. Pat. No.6,009,568, U.S. Pat. No. 5,946,740, U.S. Pat. No. 5,842,235, there areproblems in respect to costs, usage and maintenance owing to the factthat they have complex structure.

OBJECT OF THE INVENTION

The object of this invention is to provide required attachment in orderto apply slow closing damper system to existing toilet covers. It isaimed that by this attachment slow closing damper hinge can be used onexisting toilet covers without any modification and easy assembly anddisassembly possibility is provided.

Invention relates to slow closing mechanism for toilet covers (A), ahinge frame designed to make use of slow closing damper (7) in existingtoilet covers of Vitra® or other brand names. It is aimed that to ensureslow closing damper (7) supplied from the market is seated in housings(5) and to prevent releasing from recesses hereof unintentionally.

Slow closing mechanism (A) according to FIG. 1 comprises left hingeshaft (1), right hinge shaft (2), main frame (3) and slotted feet fortoilet mounting (4) on the main frame (3), damper housings (5),compressing member (6) and slow closing dampers (7) (shown in FIG. 2).

As shown in FIG. 2, main frame (3) consists of two slotted feet fortoilet mounting (4) which attachment channels extend thereon, preferablya frame which is jointed as hollow rectangular parallelepiped and hollowhalf cylinder, receiving gap (17) for damper housings, hole (15) for theleft hinge shaft on the left side and hole (16) for the right hingeshaft on the right side.

-   Left hinge shaft (1) is of four-staged structure which consists of    surface a (1 a) of the left hinge shaft in a cylindrical form,    surface b (1 b) of the left hinge shaft in a hexagonal form, surface    c (1 c) of the left hinge shaft in a cylindrical form and surface d    (1 d) of the left hinge shaft in a cylindrical form.

Right hinge shaft (2) is of four-staged structure which consists of thesurface a (2 a) of the right hinge shaft in a hexagonal form, surface b(2 b) of the right hinge shaft in a cylindrical form, surface c (2 c) ofthe right hinge shaft in a cylindrical form and surface d (2 d) of theright hinge shaft in a cylindrical form.

Slow closing dampers (7) are made of an elastic polymeric material in acylindrical form.

Damper housings (5) have a gap of semi-circle shape which slow closingdampers (7) are secured tightly thereon, have a structure to be placedin receiving gap (17) of damper housings (3) on the main frame.

Compressing member (6) as in. FIGS. 2 and 3 is capable of being placedbetween damper housings (5) attached to the main frame (3) andcompressing slow closing dampers with the end surfaces (6 a, 6 b) of thecompressing member.

As shown in FIGS. 1 and 3, left hinge shaft (1) is attached to the mainframe (3) such that surface d (1 d) of the left hinge shaft remains inthe main frame (3) and surfaces (1 a, 1 b, 1 c) of the left hinge shaftprotrude from the hole (15) for the left hinge shaft. The diameter ofthe hole (15) for the left hinge shaft is smaller than the diameter ofsurface d (1 d) of the left hinge shaft and greater than the diameter ofthe surfaces (1 a, lb, 1 c) of the left hinge shaft. Right hinge shaft(2) is attached to the main frame (3) such that surface d (2 d) of theright hinge shaft remains in the main frame (3) and surfaces (2 a, 2 b,2 c) of the right hinge shaft protrude from the hole (16) of the righthinge shaft. The diameter of the hole (16) for the right hinge shaft issmaller than the diameter of the surface d (2 d) of the right hingeshaft and greater than the diameter of surfaces (2 a, 2 b, 2 c) of theright hinge shaft.

Mechanism in the main frame (3) as in FIG. 2 is acquired when the slowclosing dampers (7) as in FIG. 2 are seated tightly in damper housings(5) and in a situated position through damper housings (5) as in FIG. 3by the capability of compressing member (6) as in FIG. 3 to be receivedbetween damper housings (5). Rotational movements of left hinge shaft(1) and right hinge shaft (2) are slowed down by the capability of endsurfaces (6 a, 6 b) of compressing member to compress the slow closingdampers (7) between the left and right hinge shafts (1, 2) in the mainframe (3).

In smooth closing mechanism (A) as in FIG. 4, right hinge arm (11) ofthe bottom cover and left hinge arm (12) of the bottom cover areattached to the bottom cover (14) of the toilet. Right hinge arm (11) ofthe bottom cover is attached to the surface b (2 b) of the right hingeshaft by free coupling. The left hinge arm (12) of the bottom cover isalso attached to the surface b of the left hinge shaft (1 b). Since thehole where the left hinge arm (12) of the bottom cover is attached tosurface b (1 b) of the left hinge shaft is hexagonal as surface b (1 b)of the left hinge shaft, bottom cover and the left hinge arm (14) havecapability to provide the rotational movement of the left hinge shaft(1). Consequently, bottom cover (14) has a property of slow closing andopening.

In smooth closing mechanism (A) as in FIG. 4, right hinge arm (10) ofthe top cover and left hinge arm (13) of the top cover are attached tothe top cover (8) of the toilet. Right hinge arm (10) of the top coveris attached to the surface a (2 a) of the right hinge shaft. The lefthinge arm (13) of the top cover is also attached to the surface a (1 a)of the left hinge shaft (1 b) by free coupling. Since the hole where theright hinge arm (10) of the top cover is attached to surface a (1 a) ofthe right hinge shaft is hexagonal as surface a (1 a) of the right hingeshaft, top cover (8) and the right hinge arm (8) of the top cover havecapability to provide a rotational movement of the right hinge shaft(2). Consequently, top cover (8) has a property of slow closing andopening.

The channels at the slotted feet for toilet mounting (4) on the mainframe (3) as in FIG. 4 are used to secure the screws (9) on the toilet.

Preferred slow closing mechanism (A) for toilet covers above is notintended to limit the protection scope of the invention. In view of thedescribed knowledge by the invention, all modifications on thispreferred slow closing mechanism (A) should be interpreted in theprotection scope of the invention.
